Lightning protection device for high-rise building

The utility model discloses a high-rise building lightning protection device which comprises an installation plate, a fixing column, a supporting column and a positioning block, the top of the installation plate is movably connected with the bottom of the fixing column, the top of the fixing column is fixedly connected with the bottom of the supporting column, the top of the installation plate is fixedly connected with the bottom of the positioning block, and a positioning cavity is formed in the positioning block. And an adjusting mechanism and a positioning mechanism are arranged in the positioning cavity. Through cooperative use of the mounting plate, the fixing column, the supporting column, the positioning block, the adjusting mechanism and the positioning mechanism, the problems that the working risk is increased and the personal safety of constructors cannot be protected due to the fact that constructors need to construct at a high place for a long time in an existing lightning rod mounting mode are so
